Inserted a div which pops up whenever the error count after validation is >1.
Added an alert div which will be displayed after a successful track.
Need to extend with fading out and resetting the form.
Added a rule to center the alert div after tracking is successful.
Added a rule to center the red div which appears when are some fields not correctly filled.
Eliminated empty elements from the array.
The empty element are present by default.
When an item has been tracked without errors a modal dialog is shown.
If we have at least on error in the form the "erralert" div will be visible.
Slightly modified "on success" after the ajax request.
We check additionally if the success status of the response is "true" before moving
to next things, if not an alert box pops out with the text of the error from the server.
Button more centered.
